. BOTTLE-SEAL.

To all whom it may concern Be it known that I, LEONARD BARTLETT, of

i Chicago, in the county" of Cook and State of i of the spring fingers will engage the thumb Illinois, have invented a new "and useful Bottle-Seal, of which the following is a specification. v V

This invention relates to seals for bottles of the character known as crown seals;

and the object of the invention is to provide a seal of thiskind with an integral thumb piece for detaching purposes so constructed thatthe seal may be applied to a bottle by I any hand-fed crown capping machine.

Myinvention is illustrated in the accompanying drawing, in which Figure 1, is an elevation of my improved seal with integral thumb piece; and Fig. 2,

is a vertical section of the same, and an illustrationof how the same is placed in a throat shown diagramma ticallyof a hand fed machine.

Like numerals of reference refer to the same parts in each of the views.

In practice Iprovide aseal consisting of a'shell 3g'provided with a crimped skirt l,

'and sealing disk, or gasket 5.

Integralwith the skirt 4:, is a thumb piece 6, preferably havingaflaring portion 7, at the bottom so that it can be readily engaged for removal from the bottle.

I am aware that it has been known to make a bottle seal'with a thumb piece for the purpose of removal; but in such cases, owing to the necessary width of the thumb piece it has been impossible to utilize a handfed throat used in crown capping machines to apply the seal to a bottle owing to the fact that the throats used in machines of this kind are provided withspring fingers adapted to engage andhold the seal in place while the bottle is being placed in. position for capping. As generally constructed, throats of this kind have four spring fingersadapt.

ed to project into the throat to support the cap after insertion by the finger. Owing to the necessary width of a thumb piece, one

piece while the others will rest in under it. This will cause the seal to be tipped owing to the pressure exerted on the thumb piece by the spring finger thereby preventing the right positioning of the seal for application.

It is the object of this invention to provide a seal which will overcome this difli culty, and, at the same time, provide for the m Specification ofLetters, Patent. Application filed gctober 4, 1913. Serial No. 793,383.

more accurate locking of the"same on the bOtt16.' i

To meet all these requirements I provide a thumb piece with an openings, therethrough, extending from the skirt of the cap to a distance suflicient to allow or one of the spring fingers 9, of a throat, as 10, to enter therein; and the skirt of the cap 3, is formed exactly the same above the opening 8, as at other points so that when the A seal is forced into locking contact with a bottle the portion 11, of the skirt will engage the bottle just the same as other portions of the skirt 4, outside the thumb piece; and in order to form the thumb piece 6, in this way with a sufliciently large opening to permit the entrance of one of the fingers 9, unrestrictedly, and yet not have it extend too far around the skirt of the cap, I have ribbed the portions of the thumb piece at each side of the opening 8, to strengthen the same.

By providing the ribs 12, the portions 13,

. of the thumb piece can be made quite narrow and yet be quite rigid when it is desired to remove the seal from the bottle, as will be understood.

As illustrated in Fig. 2, diagrammatically, the seal is always inserted by one finger, as 14, in the throat. These throats are always mounted in a capping machine with one of the spring fingers 9, toward the operator, and another directly opposite. In handling a seal of the kind here shown the operator invariably takes the seal in his hand with the thumb piece at the farthest point from him. Thus, when the seal is inserted in the throat, the opening 8, is always in the right position for the entrance of the spring finger 9, opposite the operator, and the seal is seated Y naturally in the throat in the right position for application. When applied, the portion 11, of the skirt is forced into just the same engagement as portions outside the thumb piece; and a secure engagement is made with the bottle as the metal forming the crimped skirt will flow under pressure from the capping throat without the hindrance that would occur if the thumb piece was in engagement with the skirt of the cap all the way across.

I claim:

1. In a bottle seal, a cap having a crimped skirt and an integral thumb piece, said thumb piece having an opening therethrough ending at the bottom of the skirt of said cap and suflicient in size to receive the holding finger of a cappingtool, for the purpose set forth.

2. In a bottle seal, a cap having a crimped skirt and an integral thumb piece with an opening therethrough terminating at the bottom of the skirt whereby said cap is provided With a free crimped portion above said opening, for the purpose set forth.

3. The herein described bottle seal comprising a cap and gasket, said cap having an integral thumb piece connected therewith at two points whereby an openingis formed between said connecting points With a p0r- Goplci of this patent may be obtained for five cents each, by addressing I Washington, 10.

tion of the edge of the skirt o f" the cap finger of a capping tool, the portions connecting said thumb piece and cap being ribbed whereby the requisite stiffness is obtained with a maximum amount of the edge of said'skirt exposed. I I
